NAME

STATUS CODES

* $GSL_SUCCESS
    Success

* $GSL_FAILURE
    General Failure

* $GSL_CONTINUE
    Iteration has not converged

* $GSL_EDOM
    Domain error; used by mathematical functions when an argument value does not fall into the domain over which the function is defined (like EDOM in the C library)

* $GSL_ERANGE
    Range error; used by mathematical functions when the result value is not representable because of overflow or underflow (like ERANGE in the C library)

* $GSL_EFAULT
    Invalid Pointer

* $GSL_EINVAL
    Invalid argument. This is used to indicate various kinds of problems with passing the wrong argument to a library function (like EINVAL in the C library).Invalid argument. This is used to indicate various kinds of problems with passing the wrong argument to a library function (like EINVAL in the C library).

* $GSL_EFAILED
    Generic Failure

* $GSL_EFACTOR
    Factorization Failed

* $GSL_ESANITY
    Sanity Check Failed

* $GSL_ENOMEM
    No memory available. The system cannot allocate more virtual memory because its capacity is full (like ENOMEM in the C library). This error is reported when a GSL routine encounters problems when trying to allocate memory with malloc.

* $GSL_EBADFUNC
    Problem with user-supplied function

* $GSL_ERUNAWAY
    Iterative process is our of control

* $GSL_EMAXITER
    Exceeded max number of iterations

* $GSL_EZERODIV
    Division by zero

* $GSL_EBADTOL
    Invalid user-specified tolerance

* $GSL_ETOL
    Failed to reach the specified tolerance

* $GSL_EUNDRFLW
    Underflow

* $GSL_EOVRFLW
    Overflow

* $GSL_ELOSS
    Loss of accuracy

* $GSL_EROUND
    Failed due to roundoff error

* $GSL_EBADLEN
    Matrix/vector lengths not compatible

* $GSL_ENOTSQR
    Not a square matrix

* $GSL_ESING
    Singularity Detected

* $GSL_EDIVERGE
    Integral/Series is divergent

* $GSL_EUNSUP
    Not supported by hardware

* $GSL_EUNIMPL
    Not implemented

* $GSL_ECACHE
    Cache limit exceeded

* $GSL_ETABLE
    Table limit exceeded

* $GSL_ENOPROG
    Iteration not converging

* $GSL_ENOPROGJ
    Jacobian not improving solution

* $GSL_ETOLF
    Cannot reach tolerance in F

* $GSL_ETOLX
    Cannot reach tolerance in X

* $GSL_ETOLG
    Cannot reach tolerance in Gradient

* $GSL_EOF
    End of file

FUNCTIONS

* gsl_error
* gsl_stream_printf
* gsl_strerror($gsl_errno) - This function returns a pointer to a string describing the error code gsl_errno. For example, print ("error: gsl_strerror ($status)\n"); would print an error message like error: output range error for a status value of GSL_ERANGE.
* gsl_set_error_handler
* gsl_set_error_handler_off() - This function turns off the error handler by defining an error handler which does nothing. This will cause the program to continue after any error, so the return values from any library routines must be checked. This is the recommended behavior for production programs. The previous handler is returned (so that you can restore it later).
* gsl_set_stream_handler
* gsl_set_stream
